Windows 10 Creating your own file hashing "program"

Staff Member

I personally need to generate file hashes quite a bit for verifying file integrity as well as analyzing malware samples. I really wanted to have code that I had complete control over so I wrote a short powershell script and some minor registry editing to set this up.

Registry Change If you want the change to be computer wide then edit HKCR\*\shell or to create context menu entries you will edit HKCU\SOFTWARE\Classes\*\shell.

Under shell create a new key for each context menu item you wish to create. I've added Calculate MD5, Calculate SHA1, Calculate SHA256 and Calculate SHA512
